Filed Feb. 4, 1957, Ser. No. 638,043 1 Claim. (Cl. 154--53.5)

The present invention relates to a pressure-sensitive adhesive tapehandle construction, and it particularly relates to a pressure-sensitiveadhesive tape handle construction which may be utilized for carryingpackages or other tying or binding purposes in connection with thecarrying of packages or the provision of handles for various types ofenclosures, boxes, packages and the like.

' It is among the objects of the present invention to provide a simple,laminated tape construction which may be readily manufactured on a largescale by available coating and heating machinery and which maybe'readily utilizedfor attachment to containers, packages, wrappers andthe like to provide a convenient handle, by means of which such packagesmay be both sealed and carried.

' Another object is to provide a convenient, readily applied, laminatedhandle construction for boxes, containers or other enclosures which willoccupy small space in merchandising, shipping and storage, and yet maybe readily applied to such package, box or other container as a handleas well as a sealing member.

Still further objects and advantages will appear in the more detaileddescription set forth below, it being understood, however, that thismore detailed description is given by way of illustration andexplanation only and not by way of limitation, since various changestherein may be made by those skilled in the art without departing fromthe scope and spirit of the present invention.

, In accomplishing the above objects it has been found most satisfactoryto provide a laminated tape construction which will have a re-enforced,strengthened base portion and a removable cover portion, part of all ofwhich may be removed, depending upon whether the tape is to be used as ahandle or a binding.

The base sturucture consists of a filament tape having a sheet materialbase of paper, synthetic sheet plastic material, cellophane, or evenwoven or matted fabric, which in the preferred form desirably carries aplurality of closely placed parallel rayon, nylon, glass or other fibersrunning continuously through the entire length of the tape, desirably infilament form rather than in spun form.

These filaments, which extend through the tape longitudinally of themajor axis thereof and which are positioned closely spaced together orin side by side relationship, are desirably imbedded in an elastic,pressure-sensitive adhesive and are laminated to the base sheet whichmay be in the preferred form a smooth cellophane or regeneratedcellulose or cellulose acetate backing.

Such a base laminated filament re-enforced backing tape, with apressure-sensitive adhesive facing, has great shock and tear resistanceand may be used both for packaging and carrying relatively heavycontainers or articles.

It cannot be readily ripped and must be cut, and when applied to apackage or to a paper surface of a carton or wrapper will setpermanently and become substantially an integral part of the packageitself, while re-enforcing the portions of the package to which it isattached.

In the preferred form of the invention, the pressure sensitive adhesiveis coated with a sheet of material which may be readily removed in partor whole without difficulty from the pressure-sensitive adhesive facing.

Although the cover for the pressure-sensitive adhesive coating maywidely vary, it has been found that a craft or crepe paper with thegrain extending transversely to the longitudinal axis of the material ismost satisfactory.

In the preferred form, a series of scoring or cut lines are provided inthe crepe or other removable facing so that portions of such facing maybe removed by themselves to enable the pressure-sensitive adhesive to beapplied in the form of a handle to a carton or package with theuncovered, pressure-sensitive adhesive face portions being directlyattached to the carton or paper wrapper and the unremoved facing servingas a contact against the hand for handle carrying purposes.

With the foregoing and other objects in view, the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described, and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which fall within the scope of the claim hereuntoappended.

In the drawings wherein like reference characters de note correspondingparts throughout the several views:

FIG. 1 is a top perspective view of a package with the handleconstruction of the present invention applied thereto.

FIG. 2 is a perspective view of the handle construction with the endcovering portions in position but split so that they may be readilyremoved from the balance of the liner.

FIG. 3 is a top perspective view of the handle construction with the endscore portions removed and the pressure-sensitive facing exposed withthe intermediate portion of the covering strip being still in positionto serve to contact the hand when used as a handle.

FIG. 4 is a transverse vertical sectional view upon an enlarged scaleupon the line 44 of FIG. 3.

FIG. 5 is a plan view with one of the end portions partly torn away,indicating how a plurality of handle units may be held as a single stripconstruction.

FIG. 6 is a top plan view showing a strip with a plurality of tear orscore lines enabling portions of the cover ing material to be removed atwill to give various lengths of handles to match various package sizes.

FIG. 7 is a top perspective view showing a double grip tape constructionwith a tear line, said construction being suitable for doubleapplication at each end to a relatively thinarticle to be carried.

FIG. 8 is an illustration of FIG. 7, showing the means of separating thepressure-sensitiveadhesive portions so that they may be attached on anelement to be carried or lifted.

FIG. 9 is a side perspective view indicating the application of FIGS. 7and 8 to a relatively thin package construction.

In FIG. 1 there is shown a package or carton A, a binding or sealingstrip B and a handle construction C having the connected ends D and thelifting or handle portion E. Y

The strip before application is illustrated in FIGS. 2, 3 and 4. Thestrip as shown in FIGS. 2, 3 and 4 consists of a sheet plastic or sheetfabric material 10 having a pressure-sensitive adhesive surfacing 11which carries a plurality of closely spaced parallel re-enforcingthreads or filaments or rayon, nylon or glass fiber or other filamentmaterials.

These parallel re-inforcing threads or filaments may be included in thebody of the base fabric material 10 as indicated at 12 in FIG. 4 or theymay be placed in the adhesive material or facing 11 or both.

Covering the adhesive facing 11 is a paper or other covering material 13which desirably has a grain as indicated at 14 extending transversely tothe grain or direction of the filaments or fibers 12.

Normally, the sheet plastic 10, whether it be regenerated cellulose orcellulose acetate, is coated with the adhesive 11 and the filaments 12are imbedded therein. Then the crepe paper or other removable paperfacing 13 is applied thereto and it may be scored or slit as indicatedat 15. The prepared handle, as shown in FIG. 2, then is ready forattachment to a package, as indicated at A, by removing the covering endportions 16 to convert it into the form as shown in FIG. 3.

In FIG. is shown a series of strips, such as indicated at FIG. 2, whichare mounted in a block or group as indicated at 17, and which may beripped apart along the tear lines 18.

Each of these strips are provided with the transverse cut lines orperforation lines so that the end covering portions 20 may be removed togive a series of strips, such as indicated inFIGS. 2 and 3.

In the structure shown in FIG. 6 the strip is provided with varyingspaceperforations 21, 22 and 23 which permit the various lengths of exposedpressure-sens} tive adhesive material to be provided to match differentsizes of packages or containers and to I give varying lengths ofhandles.

In the embodiment shown in FIG. 7 there is a double grip type of devicewith two laminated structures 24 which have outer smooth faces 25 andinside pressuresensitive faces 26 which are separated by a central coverstrip 27.

When the two faces 26 are removed from the central facing cover strip 27which may be ripped off at the tear line 28, there will be formed adouble attachment such as indicated at FIG. 9 which permits both sides30 or the end 31 of the handle member 32 to be attached to oppositesides 33 of a thin package or object 34 to be carried.

In the embodiment of FIGS. 7 and 8 which is applied as indicated in FIG.9 there are two strips which have inside pressure sensitive adhesivefaces 26 when the cenfor cover strip 27 is removed. The center coverstrip 27 which separates the pressure-adhesive faces after being rippedoff of the tear line 28 permits the faces to be applied to oppositesides 33 to a package or object 34.

The outer face 25 is left in position in the handle portion 39 to giveextra strength to the handle. Both the outer layer 25 as well as thecenter portion 27 are removed when the handle is applied in FIG. 9. Thecover 25 may terminate at the side edges although in FIG. 7, it is shownas being turned inwardly to form the facing cover strip 27.

In the embodiment in FIG. 7 the strip 25 covers both sides of the strip26. The laminated structure 24 which has the top face 25 is repeated atboth top and bottom in the laminated structure of FIGS. 7 and 8 with thenumeral 24 indicating the entire structure and the face of the structurebeing indicated by the numeral 25.

' It is thus apparent that the. applicant has provided a simple,reliable, convenient handle and binding construction.

The same strips, if desired, may have the paper facing 13 altogetherremoved and the entire length of the strip may be used for re-enforcing,bundling or holding purposes. However, the principal advantage residesin holding a central section, such as indicated at 13 in FIGS.

4 2 and 3, in position so that the strip may serve as a handle, asindicated in FIG. 1.

However, the base element carrying the pressure-sensitive adhesivecoating or the covering face may be made of sheet plastic materials orwoven or matted fabrics or paper materials, whether smooth or crepe. Theimportant feature is to provide cuts at the ends of the strips so as toallow the liner from both ends to be picked off the tape which is notcut, exposing a live adhesive at both ends.

These sections are attached to both ends of a carton and the centerportion which does not have the liner removed still has the backing inposition and carries the facing part of the handle.

The handles may be of various sizes and widths, and, if desired, aplurality of handles may be used in combination.

As many changes could be made in the above pressuresensitive adhesivetape handle construction, and many widely different embodiments of thisinvention could be made without departure from the scope of the claim,it is intended that all matter contained in the above description shallbe interpreted as illustrative and not in a limiting sense.

Having now particularly described and ascertained the nature of theinvention, and in what manner the same is to be performed, what isclaimed is:

In a paper wrapped package, a three ply pressure-sensitive-adhesiveattached trilaminate handle structure comprising a trilaminate tapehaving a central handle portion and end pressure-sensitive-adhesiveportions, the entire length of the tape having an elongated base stripcarrying on its inside face a pressure-sensitive-adhesive and alsointegrally carrying a plurality of closely spaced parallellongitudinally extending filaments and having an inside crepe paperunder-cover for said pressure-sensitive-adhesive with a grain transverseto said filaments, the portions of said under-cover in the end portionsbeing removable to enable said end portions to be attached to a paperwrapped package and the portions of said under-cover in the handleportion serving to contact the hand when the handle portion is utilizedto carry a package, said base strip being cellulose acetate and havingembedded in the body thereof said parallel filaments.
